ASA 5500 analyze traffic?

[kmacdonald]

We have a Cisco ASA 5510 security device.

Here recently it seems every day at the same time (between 3 and 4 pm) our internet connection (4 bonded t1's) comes to a crawl.  I've looked through the Cisco but haven't been able to find anything useful.  I'd like to see what internal clients are accessing what externally and maybe see a bandwidth report for each client.  Is this possible?  I'd like to track down what is going on at these times.  We never had this problem before I implemented the ASA about 4 months ago.  I doubt it is the device, I just need to know what is going on and the only way I can think of doing so is running some report from the ASA.

Thanks!

well i think a goo dpoint to start would be ask your isp/service provider to give you a stats of traffic around that time

this will give you a good idea about bandwidth utilzation of your T1

try to find out what is happening between 3 to 4 pm in your network, many times there could be scheduled backups happening at fixed times in a day and this traffi cmight be too much and overloading the firewall

check the following during this time

logs - to see if you find something wierd

cpu -see how it fares betwene 3-4 pm when compared to rest of the day

show xlate - again as above

show conn - again as above

and my final answer if you have smartnet - open TAC CASE - we will be more than happy to investigate

Hi,

Just to add on here, ASDM has some important graphs which might help you as well.

As seen, you can see TOP access-list hits, Top USage (including source address, dest address and service). Hope this helps.
